Abstract
A camshaft assembly for attachment to a cylinder head of an internal combustion engine, the camshaft assembly includes a one-piece camshaft bearing cap having an internal bearing surface sized to receive a portion of a camshaft therein, the internal bearing surface configured to support the portion of the camshaft between 180 degrees and 360 degrees circumferentially. The one-piece camshaft bearing cap is removable from the camshaft to enable line of sight access by an operator to the cylinder head. The internal bearing surface has oil supply grooves fluidly coupled to drillings for operation of a cam phaser assembled with a drive member and the camshaft. Head bolts are used to attach the cylinder head to the engine and are accessible upon removal of the camshaft bearing cap and camshaft. Standard camshaft bearing caps can be assembled with the camshaft and the cylinder head at various attachment points.
